In Edinburgh the whole 'to-thank-or-not-to-thank' dilemma is solved by having exit doors in the middle of the bus. Communication with the drivers seems to be strictly discouraged, in fact, by virtue of them sitting in a perspex isobooth. Your fare is poured into a slot, whereupon the driver presses a button to signal its descent down the chute of destiny into the locked safe of eternity (they don't, famously, give change). The ticket appears from a hole in the wall. The whole thing works so that even eye contact with the driver is a near impossibility... I quite like it that way.

In a more civilised and less cost-conscious world we'd have bus conductors and the driver could get on with his job undistracted, and undelayed.

I had the eerie experience last night of travelling on a coach whose driver had the exact same name as me. I'd never met anyone else with my name before. It's decidedly creepy.

My colleagues googled me and discovered someone with my name that they claim also looks exactly like me. I dispute this (not only because he's over 50 and American). But I'm still slightly disturbed.

Someone with my name draws Harry Potter fan art. Someone else is a pop star. And another one is head of a Meat Board (?) or something, if I remember correctly. But I'm the best one. :)

Whereas I (as could a great many people I suspect) can be fairly sure that my name is unique, even if we discount my middle name. Anybody with my surname is a member of my father's-side family and due to cultural/ethnic reasons, the probability of any of them sharing my first name is extremely low.

According to google, I have one phonetic namesake (ie her name is spelled wrong) who's a successful college runner in the US. Anyone who knows me will know she's not me as I'm crap at running, whereas I am rather brilliant at writing - she doesn't have any google-indexed articles published on the Institute of Biology's website.
